Aero geophysical data is becoming an important source of environmental covariate in digital mapping. Airborne gamma-ray spectrometry is more common in digital soil mapping, because of the penetration potential of approximately 30-40 cm. However, the airborne magnetic method can be tested to add and improve the prediction of soil properties. Therefore, the objective of this work was to implement a preliminary study to model the spatial distribution of soil properties using pedological legacy data, aero geophysical data, and terrain covariates to discuss their importance to the digital soil mapping in Bom Jardim county, Rio de Janeiro, Brazil. |

The objective of this work was to characterize two Phytophthora palmivora isolates causing floral blight and rot in azalea plants and to evaluate the pathogenicity of this oomycete pathogen on several plant species. Azalea plants with symptoms of flower blight and rot were obtained in the municipality of Holambra-SP. After an attempt of isolation, colonies with Phytophthora characteristics grown only on selective V8 medium. Molecular identification of the isolates was done by amplification and sequencing of ITS and COX2 regions. In the phylogenetic analysis, the azalea isolates clustered with reference isolates of P. palmivora. Morphological characteristics were similar to those described for P. palmivora. Isolates were inoculated in healthy azalea plants and caused leaf blight and floral rot. The pathogen was re-isolated from symptomatic plants completing Koch?s postulates. In a host range test, the azalea isolateswere able to cause lesions on leaves of vinca, snapdragon, basil, and tomato, and affected both leaves and flowers of geranium. Fruit rot was observed on tomato, potato, sweet pepper, scarlet eggplant, zucchini, cucumber, maroon cucumber, onion, apple, papaya, guava, and carrot. This is the first report of the species P. palmivora causing flower blight and rot in azalea plants in Brazil and probably in the world. |
